  1. Panda Grid Status Kilian Schwarz, GSI on behalf of PANDA GRID Group (slides to a large extend from Radoslaw Karabowicz)

  2. Central services, LDAP, DB and ML transfers • Phone meeting on 1st Feb 2012 • Till end of February GRID management center has to be moved out of Glasgow, including: • Lightweight Directory Access Protocol (LDAP) -> GSI • MySQL DataBases (DB) -> GSI, Torino • Alien2 Central Services (CS) -> GSI • PANDA GRID MonaLisa (ML) -> Jülich

  3. Panda GRID @ GSI • Central Services installation status after the May Panda GRID meeting: • Lightweight Directory Access Protocol (LDAP) -> GSI • MySQL DataBases (DB) -> GSI, Torino • AliEn2 Central Services (CS) -> GSI • PANDA GRID MonaLisa (ML) -> Jülich / Torino • Recent changes of AliEn required direct interventions of the CERN people to our MySQL and our machine settings - still working to bring the Panda GRID back

  4. Panda GRID Map ~12 sites ~1400 CPUs SC, LDAP, DB in GSI

Also, the job counter started from 0 again.

  6. PandaRoot @ GRID Installed: panda_extern: apr08, jul08, jul09, may11, jan12 pandaroot: may11, july11,august11 nov11, stable, trunk (updated every Tuesday with results published in pandaroot cdash)

  7. GRID Disk Usage

  8. needed • more GRID users • and we have to regain the users trust after a longer period of only partial functionality • http://panda-wiki.gsi.de/cgi-bin/view/Computing/PandaGridAliEn2ClientInstall • more sites • http://panda-wiki.gsi.de/cgi-bin/view/Computing/PandaGridAliEn2SiteInstall • GRID developers

  9. ALICE & PANDA • The PANDA-ALICE relationship: • we use middleware written by ALICE • we have our own requirements and requests • we are supposed to give back: • allocate dedicated manpower for middleware development and user support • manpower will come also via LSDMA • develop in-house expertise with this middleware, and not only as users • debug and develop AliEn: Oracle Interface, Slurm Interface, PoD interface, VO-VO interface • PANDA uses already AliEn v2-20 and is debugging this for ALICE

  10. Issues • masterjob –printsite does not work • fquota does not work properly for many users • “services” command not working • packman install –everywhere does not work • job triggered installation is not sufficient for PANDA since we compile on site • AliEn installer installation works only with manual fixes (Gnu.so ...) • masterSE replicate

  11. Issues #2 • some sites still do not take jobs • Deletion of files • inter site data transfer/mirror • ROOT API • packages list in ML • activation of backup DB

  12. wish list • JAliEn • To be able to install specific revision number via AliEn installer

  13. conclusion • ALICE/FAIR collaboration also in context of Grid computing works quite well • Still there is room for improvement • PANDA can not be beta tester within its production environment • common testbed maintained by ALICE and PANDA ? • information flow needs to be improved. We can not always be taken by surprise if there is some majore change in the AliEn DB • how to solve all the existing issues ? Currently we put them all in the GSI ticketing system. Who is responsible for what ?
